body cavities1
BODY CAVITIES
  • Spaces within the body containing vital organs
  • Two MAIN Cavities
    • Dorsal – (posterior) on

the back side of the body

      • Cranial – holds the brain
      • Spinal Cavity – holds the

spinal cord

body cavities2
BODY CAVITIES

Two MAIN Cavities

  • Ventral – (anterior) on the belly side of the body
    • Thoracic – holds the heart, lungs, and major blood vessels
    • Abdominal – holds organs of the digestive & urinary systems
      • Stomach, small intestines, liver, gallbladder, pancreas, spleen, & part of the large intestine
    • Pelvic – contains the urinary bladder, reproductive organs, rectum, remaining part of the large intestine & the appendix
body planes1
BODY PLANES
  • Fixed lines of reference along which the body is often divided or sectioned
  • Allows for a three-dimensional perspective
sagittal medial plane
SAGITTAL - MEDIAL PLANE
  • Divides the body into two parts
    • Left & Right
midsagittal plane
MIDSAGITTAL PLANE
  • Divides the body into EQUAL left and right halves
frontal or coronal plane
FRONTAL orCORONAL PLANE
  • Divides the body into anterior and posterior sections
transverse plane
TRANSVERSE PLANE
  • Divides body into top (superior) and bottom (inferior) parts
anatomical position
ANATOMICAL POSITION
  • Standing erect
  • Facing forward
  • Arms at side
  • Palms forward
anterior ventral
ANTERIOR/VENTRAL
  • Means to the front (belly) side of the body
posterior dorsal
POSTERIOR/DORSAL
  • Means the back side of the body
superior
SUPERIOR
  • Above another structure
inferior
INFERIOR
  • Below another structure
lateral
LATERAL
  • Means to the side
medial
MEDIAL
  • Means middle or near the medial plane
proximal
PROXIMAL
  • Means near the point of attachment to the trunk
distal
DISTAL
  • Means away from the point of attachment to the trunk
supine

SUPINE

Means lying on the back facing upward

prone

PRONE

Means lying on the stomach facing downward

slide24

DEEP

Means through the surface

superficial

SUPERFICIAL

Means on or near the surface

cranial cephalic
CRANIALCEPHALIC
  • Meaning toward the head
caudal
CAUDAL
  • Meaning toward the feet
regions1
REGIONS
  • Abdominal cavity is divided into nine regions
  • Regions are used to describe the location of the organ, injury or pain
epigastric
EPIGASTRIC
  • Upper, center area above the stomach
umbilical
UMBILICAL
  • The region surrounding the umbilicus
hypogastric
HYPOGASTRIC
  • Area just below the umbilical region
hypochondriac
HYPOCHONDRIAC
  • Just below the ribs, immediately over the abdomen
  • On either side of the epigastric region
  • A left and a right side
lumbar
LUMBAR
  • Near the waist
  • On either side of the umbilical region
  • A left and a right side
iliac or inguinal
ILIAC or INGUINAL
  • Located near the upper portion of the hipbone
  • On either side of the hypogastric region
  • A left and a right side
quadrants1
QUADRANTS
  • A simpler way to divide the abdominal cavity is into QUADRANTS
right upper quadrant ruq
Right Upper Quadrant (RUQ)
  • On the right anterior side
    • Contains part of the liver, the gallbladder, parts of the pancreas and intestinal tract
right lower quadrant rlq
Right Lower Quadrant (RLQ)
  • On the right anterior side
    • Contains the appendix, parts of the intestines, female reproductive organs and the urinary tract
left upper quadrant luq
Left Upper Quadrant (LUQ)
  • On the left anterior side
    • Contains the stomach, spleen, and parts of the liver, pancreas and intestines
left lower quadrant llq
Left Lower Quadrant (LLQ)
  • On the left anterior side
    • Contains parts of the intestines, reproductive organs of the female and the urinary tract
